помогите с химией!!!! Zn+HCl = NaOHф+HCl= K2CO3+HCl= K2SO4+HCl= NaOH+H2SO4= NaOH+FeCl3= CuSO4+NaOH= CuSO4+BaCl2=

1) Zn + 2HCl = ZnCl2 +H2

2)NaOH + HCl = NaCl +H2O

3)K2CO3 + 2HCl = 2KCl +H2CO3

4)K2SO4 + 2HCl = 2KCl +H2SO4

5)NaOH + H2SO4 = NaSO4 +H2O

6) 3NaOH + Fe Cl3 = 3NaCl +Fe(OH)3

7)CuSO4 + 2NaOH = Cu(OH)2 (осадок)+ Na2SO4

8)CuSO4 + BaCl2 = CuCl2 + BaSO4(осадок)
